=head1 DESCRIPTION

This module is an implementation of the pastebin.com API
(L<http://pastebin.com/api>). The API allows creation of public,
unlisted, and private pastes; deletion of private pastes;
listing of trending pastes and private pastes; and retrieval
of a paste's raw content (the last one is not part of the API, but
is nevertheless implemented in this module).

B<NOTE ON GETTING PASTES:> Despite tons of patently useless stuff
the API provides, it doesn't offer anything but the raw contents
of the paste (not even that, if we're to get technical). If your
main aim is to B<retrieve> pastes and/or retrieve info about
pastes (e.g. expiry date, highlight, etc), then this module will not
help you. See L<WWW::Pastebin::PastebinCom::Retrieve> for that task.

=head1 API KEY NEEDED

The only method that doesn't require an API key is
C<< ->get_paste() >>. To use any other features of this module
you will need to obtain an
API key from pastebin.com. Simply create an account on pastebin.com,
login, then visit (L<http://pastebin.com/api>) and
the key will be listed somewhere in the second section on the page.
The key will look something like this:
C<a3767061e0e64fef6c266126f7e588f4>.

=head1 METHODS

=head2 C<< new >>

    # no API key
    my $bin = WWW::Pastebin::PastebinCom::API->new;

    # API key and setting timeout
    my $bin = WWW::Pastebin::PastebinCom::API->new(
        api_key =>  'a3767061e0e64fef6c266126f7e588f4',
        user_key => '4fd751dc94f0b62c489b2c7720e0d240',
        timeout => 60,
    );

    # no API key and setting scustom UA
    my $bin = WWW::Pastebin::PastebinCom::API->new(
        ua => LWP::UserAgent->new(
            timeout => $args{timeout},
            agent   => 'Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:21.0)'
                        . ' Gecko/20100101 Firefox/21.0',
        )
    );

Creates and returns a new C<WWW::Pastebin::PastebinCom::API> object.
All arguments are optional and are described below.

=head3 C<api_key>

    my $bin = WWW::Pastebin::PastebinCom::API->new(
        api_key =>  'a3767061e0e64fef6c266126f7e588f4',
    );

B<Optional>.
Takes pastebin.com's API key as a string.
By default is not specified.

You don't have to specify the key here and can use the
C<< ->api_key() >> accessor method instead, to set the key prior
to calling module methods.

The only method that doesn't require an API key is
C<< ->get_paste() >>. To use any other features of this module
you will need to obtain an
API key from pastebin.com. Simply create an account on pastebin.com,
login, then visit (L<http://pastebin.com/api>) and
the key will be listed somewhere in the second section on the page.
The key will look something like this:
C<a3767061e0e64fef6c266126f7e588f4>.

=head3 C<user_key>

    my $bin = WWW::Pastebin::PastebinCom::API->new(
        user_key => '4fd751dc94f0b62c489b2c7720e0d240',
    );

B<Optional>. Takes a user key string as a value. By default
is not specified.

To create, delete, or list private pastes, you will need a user key.
To obtain one, see C<< ->get_user_key() >> method. Pastebin.com's API
says these keys don't expire, so I would expect that you can
print one user key from C<< ->get_user_key() >>, then simply
reuse the same user key for your C<WWW::Pastebin::PastebinCom::API>
scripts, just as you do with C<api_key>. This would save making a
request to pastebin.com every time you need a user key.

=head3 C<timeout>

    my $bin = WWW::Pastebin::PastebinCom::API->new(
        timeout => 60,
    );

B<Optional>. Takes a number that represents seconds.
B<Default:> 30.

Specifies the request timeout whenever making requests to
pastebin.com.

=head3 C<ua>

    my $bin = WWW::Pastebin::PastebinCom::API->new(
        ua => LWP::UserAgent->new(
            timeout => 30,
            agent   => 'Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:21.0)'
                        . ' Gecko/20100101 Firefox/21.0',
        )
    );

B<Optional>. Takes an L<LWP::UserAgent>-compatible object. That
object must implement C<< ->post() >> and C<< ->get() >> methods
that return the same stuff L<LWP::UserAgent> returns.
B<By default> uses L<LWP::UserAgent> with C<timeout> set by
C<timeout> constructor argument (see above) and C<agent> set
to Firefox on Linux.

=head2 C<< get_paste >>

    my $bin = WWW::Pastebin::PastebinCom::API->new;
    print $bin->get_paste('http://pastebin.com/YpTmWJG6')
        || die "$bin";

    print $bin->get_paste('YpTmWJG6')
        || die "$bin";

    #### Get a private paste:
    print $bin->get_paste('YpTmWJG6', $USER, $PASS)
        || die "$bin";

Retrieves raw content of an existing paste.
B<Takes> one mandatory and two optional arguments.

The mandatory argument is a string that is either
a URL to the paste you want to retrieve or just the paste ID
(e.g. paste ID in "http://pastebin.com/YpTmWJG6" is "YpTmWJG6").
The two optional arguments must be provided together and they
are the login and the password to the pastebin.com account.
They must be provided when getting private pastes for that
account.

B<On success returns> the raw content of the paste.
B<On failure returns> either C<undef> or an empty list, depending
on the context, and C<< ->error() >> method will contain
human-readable description of the error.

The use of this method doesn't require
you to have an API key with pastebin.com.

=head2 C<< get_user_key >>

    my $bin = WWW::Pastebin::PastebinCom::API->new(
        api_key => 'a3767061e0e64fef6c266126f7e588f4',
    );

    $bin->get_user_key(qw/
        your_pastebin.com_login
        your_pastebin.com_password
    /) or die "$bin";

Obtains a user key from pastebin.com. This user key is required for
creating, deleting, and listing private user pastes. The API spec
says this key does not expire, so you should be able to reuse
one key for all your needs (see C<user_key> argument for the
constructor). B<Takes> two mandatory arguments as
strings: first
one is your pastebin.com login, second one is your pastebin.com
password. B<On success> sets C<< ->user_key() >> accessor and
returns a user key (e.g. C<4fd751dc94f0b62c489b2c7720e0d240>).
B<On failure returns> either C<undef> or an empty list, depending
on the context, and C<< ->error() >> method will contain
human-readable description of the error. Note that
if C<< ->get_user_key() >> fails, then
C<< ->user_key() >> will be undefined, even if it was set
to something prior to the call of C<< ->get_user_key() >>

=head2 C<< paste >>

    ##### Simple paste with all optional args at default values

    my $bin = WWW::Pastebin::PastebinCom::API->new(
        api_key => 'a3767061e0e64fef6c266126f7e588f4',
    );

    print $bin->paste('Stuff to paste') || die "$bin";


    ##### Make an unlisted paste

    my $bin = WWW::Pastebin::PastebinCom::API->new(
        api_key => 'a3767061e0e64fef6c266126f7e588f4',
    );

    print $bin->paste( 'Stuff to paste', unlisted => 1, )
        || die "$bin";


    ##### Private paste with all optional args set

    my $bin = WWW::Pastebin::PastebinCom::API->new(
        api_key => 'a3767061e0e64fef6c266126f7e588f4',
    );

    $bin->get_user_key(qw/
        your_pastebin.com_login
        your_pastebin.com_password
    /) or die "$bin";

    $bin->paste(
        'Stuff to paste',

        title => 'Title for your paste',
        private => 1,       # set paste as a private paste
        format => 'perl',   # Perl syntax highlighting
        expiry => 'awhile', # expire the paste after 1 week
    ) or die "$bin";

    print "$bin\n";

Creates a new paste on pastebin.com.
B<On success> sets C<< ->paste_url() >> accessor method
and returns a URL pointing to the newly-created paste.
B<On failure returns> either C<undef> or an empty list, depending
on the context, and C<< ->error() >> method will contain
human-readable description of the error. Note that on failure,
C<< ->paste_url() >> will be undefined, even if it was set prior
to executing C<< ->paste() >>. B<Takes> one
mandatory argument as a string (paste content) and several optional
arguments as key/value pairs. Possible arguments are as follows:

=head3 First argument

    print $bin->paste('Stuff to paste') || die "$bin";

B<Mandatory>. Specifies the content of the paste.

=head3 C<title>

    $bin->paste(
        'Stuff to paste',
        title => 'Title for your paste',
    ) or die "$bin";

B<Optional>. Specifies the title of the paste. B<By default> is
not specified and the paste will end up being called "Untitled."

=head3 C<expiry>

    $bin->paste(
        'Stuff to paste',
        expiry => 'asap',
    ) or die "$bin";

B<Optional>. Specifies when the paste should expire.
B<By default> is not specified, so the paste will never expire.
B<Takes> a string as an argument. Case-insensitive. Along with
values specified by the API, several other aliases exist. Possible
values are as follows:

=head4 Expire in 10 Minutes

    10m
    m10
    asap

=head4 Expire in 1 Hour

    h
    1h

=head3 C<format>

    $bin->paste(
        'Stuff to paste',
        format => 'perl',
    ) or die "$bin";

B<Optional.> Specifies syntax highlighting language. B<Takes>
a string as a value, which specifies the language to use. Possible
values are (on the left is the value you'd use for C<format>
and on the right is the explanation of what language it is):

=head3 C<unlisted>

    print $bin->paste( 'Stuff to paste', unlisted => 1, )
        || die "$bin";

B<Optional.> B<Takes> a true or false value. B<When set to>
a true value, will cause the paste to be unlisted.
When used in conjunction with C<private> option (see below)
the behaviour is undefined. B<By default> neither
C<unlisted> nor C<private> are specified and the created
paste is public and listed.

I<Note:> Pastebin will automatically list duplicate content
or content with some keywords as unlisted,
even if we tell it to go public. It's not a bug in the module.

=head3 C<owned>

    $bin->get_user_key(qw/
        your_pastebin.com_login
        your_pastebin.com_password
    /) or die "$bin";

    print $bin->paste( 'Stuff to paste', owned => 1, )
        || die "$bin";

B<Optional.> B<Takes> a true or false value.
B<When set to>
a true value, will cause the paste you create to be labeled as
pasted by you instead of C<Guest>.
B<By default> is set to false and pastes will be labeled
as created by C<Guest>.

When creating an "owned"
paste, C<< ->user_key() >>
accessor method must contain a user key for the user who will own
this paste. You can either set it directly using C<< ->user_key() >>,
set it in the constructor using C<user_key> argument, or set it
indirectly by calling C<< ->get_user_key() >> method.

=head3 C<private>

    $bin->get_user_key(qw/
        your_pastebin.com_login
        your_pastebin.com_password
    /) or die "$bin";

    print $bin->paste( 'Stuff to paste', private => 1, )
        || die "$bin";

B<Optional.> B<Takes> a true or false value.
B<When set to>
a true value, will cause the paste to be private (viewable only
when the user is logged in).
When used in conjunction with C<unlisted> option (see above)
the behaviour is undefined. B<By default> neither
C<unlisted> nor C<private> are specified and the created
paste is public and listed.

When creating a private or "owned"
paste, C<< ->user_key() >>
accessor method must contain a user key for the user who will own
this paste. You can either set it directly using C<< ->user_key() >>,
set it in the constructor using C<user_key> argument, or set it
indirectly by calling C<< ->get_user_key() >> method.

=head2 C<delete_paste>

    $bin->get_user_key(qw/
        your_pastebin.com_login
        your_pastebin.com_password
    /) or die "$bin";

    $bin->delete_paste('http://pastebin.com/YpTmWJG6')
        or die "$bin";

    #### or
    $bin->delete_paste('YpTmWJG6')
        or die "$bin";

Deletes user's private paste (see C<private> argument
to C<< ->paste() >>). B<Takes> one mandatory argument as a string
containing either the full URL to the paste to be deleted
or just the paste ID (e.g. C<YpTmWJG6> is paste ID for
C<http://pastebin.com/YpTmWJG6>).

The C<< ->user_key() >>
accessor method must contain a user key for the user who owns
this paste. You can either set it directly using C<< ->user_key() >>,
set it in the constructor using C<user_key> argument, or set it
indirectly by calling C<< ->get_user_key() >> method.

=head2 C<list_user_pastes>

    $bin->get_user_key(qw/
        your_pastebin.com_login
        your_pastebin.com_password
    /) or die "$bin";

    my $pastes = $bin->list_user_pastes(10) # get at most 10 pastes
        or die "$bin";

    use Data::Dumper;
    print Dumper $pastes;

Lists user's private pastes. Prior to calling C<< ->list_user_pastes() >>
C<< ->user_key() >> must be set, either
by calling C<< ->get_user_key() >>, using C<< ->user_key() >>
accessor method, or C<user_key> constructor argument.
B<Takes> one optional argument as a
positive integer between 1 and 1000, which specifies the
maximum number of pastes to retrieve. B<By default> will get
at most 50 pastes. B<On failure> returns either
C<undef> or an empty list, depending on the context, and the
C<< ->error() >> accessor method will contain human-readable
error message. B<On success> returns a — possibly empty — arrayref
or a list (depending on context) of hashrefs, where each hashref
represents information about a single paste. The format
of the hashref is this:

    {
        'key'           => 'zrke2Q9R',
        'url'           => 'http://pastebin.com/zrke2Q9R',
        'title'         => 'Title for your paste'
        'date'          => '1382901396',
        'expire_date'   => '1383506196',
        'format_short'  => 'perl',
        'format_long'   => 'Perl',
        'private'       => 1,
        'size'          => '14',
        'hits'          => '0',
    }

The API is not descriptive on what values these keys might have,
so what you have below is only my interpretation:

=head3 C<key>

        'key' => 'zrke2Q9R',

String of text. The paste ID of the paste. You can pass it to
C<< ->delete_paste() >> method to delete the paste.

=head3 C<url>

        'url' => 'http://pastebin.com/zrke2Q9R',

String of text. The URL of the paste.

=head3 C<title>

        'title' => 'Title for your paste'

String of text. The title of the paste.

=head3 C<date>

        'date' => '1382901396',

Unix time format. The date when the paste was created.

=head3 C<expire_date>

        'expire_date' => '1383506196',

Unix time format. The date when the paste will expire.

=head3 C<format_short>

        'format_short' => 'perl',

Syntax highlighting for the paste. See the left column in the
C<format> argument for the C<< ->paste() >> method.

=head3 C<format_long>

        'format_long' => 'Perl',

Explanation of the code for the syntax highlighting for the paste.
See the right column in the C<format> argument for
the C<< ->paste() >> method.

=head3 C<private>

        'private' => 1,

True value, if exists. An indication that it's a private paste.

=head3 C<unlisted>

        'unlisted' => 1,

True value, if exists. An indication that it's an unlisted paste.

=head3 C<size>

        'size' => '14',

Positive integer. The size of the paste, presumably the number
of characters.

=head3 C<hits>

        'hits' => '0',

Positive integer or zero. The number of times the paste was viewed.

=head2 C<list_trends>

    my $bin = WWW::Pastebin::PastebinCom::API->new(
        api_key => 'a3767061e0e64fef6c266126f7e588f4',
    );

    my $trends = $bin->list_trends
        or die "$bin";

    use Data::Dumper;
    print Dumper $trends;

Lists 18 trending pastes. B<Takes> no arguments.
B<On failure> returns either
C<undef> or an empty list, depending on the context, and the
C<< ->error() >> accessor method will contain human-readable
error message. B<On success> returns an arrayref
or a list (depending on context) of hashrefs, where each hashref
represents information about a single paste. The format
of the hashref is the same as for hashrefs returned by the
C<< ->list_user_pastes() >> method (see above), except that
that C<private>, C<format_short>, and C<format_long> keys
will not be there.

=head2 C<get_user_info>

    my $bin = WWW::Pastebin::PastebinCom::API->new(
        api_key => 'a3767061e0e64fef6c266126f7e588f4',
    );

    $bin->get_user_key(qw/
        your_pastebin.com_login
        your_pastebin.com_password
    /) or die "$bin";

    my $info = $bin->get_user_info
        or die "$bin";

    use Data::Dumper;
    print Dumper $info;

List user's account info. Prior to calling C<< ->get_user_info() >>
C<< ->user_key() >> must be set, either
by calling C<< ->get_user_key() >>, using C<< ->user_key() >>
accessor method, or C<user_key> constructor argument. B<Takes>
no arguments. B<On failure> returns either
C<undef> or an empty list, depending on the context, and the
C<< ->error() >> accessor method will contain human-readable
error message. B<On success> either a hashref or a key/value list,
depending on the context. The format of the hashref is this:

    {
        'name' => 'zoffixisawesome',
        'website' => 'http://zoffix.com',
        'location' => 'Toronto',
        'format_short' => 'perl',
        'avatar_url' => 'http://pastebin.com/i/guest.gif',
        'private' => '1',  # also possible for this to be unlisted => 1 instead
        'email' => 'cpan@zoffix.com',
        'expiration' => 'N',
        'account_type' => '0'
    }

The API is not too descriptive about
the values of the user info, so what follows is my interpretation:

=head3 C<name>

    'name' => 'zoffixisawesome',

A string of text. User's login.

=head3 C<email>

    'email' => 'cpan@zoffix.com',

A string of text. User's email address.

=head3 C<website>

    'website' => 'http://zoffix.com',

A string of text. The website the user specified in their profile.

=head3 C<location>

    'location' => 'Toronto',

A string of text. User's location (specified by the user manually
by them in their profile).

=head3 C<format_short>

    'format_short' => 'perl',

This is the code for user's default syntax highlighting. See the left
column in the C<format> argument to C<< ->paste() >> method.

=head3 C<avatar_url>

    'avatar_url' => 'http://pastebin.com/i/guest.gif',

A string of text. The URL to the user's avatar picture.

=head3 C<private> or C<unlisted>

    'private' => '1',

    'unlisted' => '1',

True value, if exist. If C<private> key is present, user's default
paste setting is to make the paste private. If C<unlisted> key is
present, user's default paste setting is to make the paste unlisted.

=head3 C<expiration>

    'expiration' => 'N',

User's default expiry setting for their pastes. The values
you can possibly get here are these:

    N = Never
    10M = 10 Minutes
    1H = 1 Hour
    1D = 1 Day
    1W = 1 Week
    2W = 2 Weeks
    1M = 1 Month

=head3 C<account_type>

    'account_type' => '0',

0 or 1 as a value. Indicates user's account type. 0 means it's a normal;
1 means PRO.

=head1 ACCESSOR METHODS

=head2 C<error>

    $bin->paste('Stuff') or die $bin->error;

    ### or

    $bin->paste('Stuff') or die "$bin";

B<Takes> no arguments. Returns the human-readable error message if
the last method failed.
This method is overloaded so you can call it by interpolating
the object in a string. The only difference is when interpolating,
the error message will be preceded with the word C<Error:>. Note
that C<< ->paste_url() >> is also overloaded and the module will
interpolate the value of instead
C<< ->paste_url() >> if no error is set.

=head2 C<paste_url>

    $bin->paste('Stuff') or die "$bin";
    print $bin->paste_url;

    ### or

    $bin->paste('Stuff') or die "$bin";
    print "$bin"

B<Takes> no arguments. Returns the URL of the newly-created paste after
a successful call to C<< ->paste() >> method.
This method is overloaded so you can call it by interpolating
the object in a string. Note
that C<< ->error() >> is also overloaded and the module will
interpolate the value of C<< ->error() >> instead, if an error is set.

=head2 C<api_key>

    my $bin = WWW::Pastebin::PastebinCom::API->new;

    $bin->api_key('a3767061e0e64fef6c266126f7e588f4');
    printf "Current API key is %s\n", $bin->api_key;

B<Takes> one optional argument as a string, which is a pastebin.com's
API key to be used by the module. B<Returns> the currently used
API key, as a string.

=head2 C<user_key>

    my $bin = WWW::Pastebin::PastebinCom::API->new(
        api_key => 'a3767061e0e64fef6c266126f7e588f4',
    );

    $bin->get_user_key(qw/
        your_pastebin.com_login
        your_pastebin.com_password
    /) or die "$bin";

    printf "Current user key is %s\n", $bin->user_key;

B<Takes> one optional argument as a string, which is a
user key to be used by the module. B<Returns> the currently used
user key, as a string. See C<< ->get_user_key() >> for details
on what a user key is.

=head1 OVERLOADS

    $bin->paste('Stuff') or die "$bin";
    print "$bin";

The C<< ->error() >> and C<< ->paste_url() >> methods are overloaded
so you can call them by interpolating the object in a string.
If C<< ->error() >> contains an error message it will be called
when the object is interpolated, otherwise C<< ->paste_url() >> will
be called. There's a slight difference between calling
C<< ->error() >> directly or through interpolation: when interpolated,
word C<Error: > is added to the error message.
